INDIANAPOLIS, Indiana – Central Indiana is gearing up for a cooler stretch of weather, with patchy fog, scattered weekend showers, and even below-50° temperatures expected early next week. While Friday and Saturday will stay warm and mostly pleasant, a fall-like pattern is just around the corner — and it’s arriving a little early this year.
Fog Expected Friday Morning
The National Weather Service in Indianapolis warns that patchy fog could develop overnight and into early Friday morning, especially in low-lying areas and along interstates near Indianapolis, Bloomington, and Lafayette.
Drivers are advised to:
Slow down and use low-beam headlights
Watch for reduced visibility near rivers and open fields
Allow extra time for morning commutes
The fog is expected to clear by mid-morning, with partly cloudy skies taking over and mild afternoon highs ranging from the upper 70s to low 80s.
Scattered Showers Possible Saturday
Saturday will start off warm and partly cloudy, with highs reaching the mid-80s in some parts of the state. However, isolated showers may pop up during the day, especially during the afternoon and evening hours.
Though these showers are not expected to be widespread or severe, they could briefly interrupt outdoor activities like sports events, markets, or barbecues.
Big Cooldown Next Week
Starting Sunday, Indiana will begin to feel a noticeable drop in temperatures. Highs will fall to the low and mid-70s, and overnight lows will dip toward the 50s, possibly even below 50°F in some rural areas by Monday morning.
This pattern will bring a fall-like chill to the air, which is unusual for late August in Indianapolis. Forecasters say this cool stretch could last much of the week, with no signs of extreme heat returning anytime soon.
